## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Undershoot, approach - vfr pattern - final approach
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - weather condition - windshear (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
- Loss of control - on ground/water, landing
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - uncontrolled, pilot in command
- On ground/water collision with object, landing - roll
  - object - building(nonresidential) (contributing factor)

## Analysis

THE PLT REPORTED THAT DURING A LANDING ON RWY 4, HE ENCOUNTERED WIND SHEAR WHICH FORCED THE ACFT TO LOSE ALT & TOUCH DOWN SHORT OF THE RWY. THE ACFT THEN VEERED LEFT & COLLIDED WITH A HANGAR. THE PLT REPORTED THE WIND WAS FROM 300 DEG AT 12 GUSTING 18 KTS. WITNESSES ADVISED THAT WIND CONDITIONS AT THE ARPT WERE UNPREDICTABLE. THE PLT SUGGESTED THAT MORE SPACE WAS NEEDED BETWEEN THE NARROW RWY & THE HANGARS.
